Atmospheres (2018)

If its of any use to anyone, a list of potential atmospheric gases and taints is provided below. Edit (and copy) for the coding:

Typical Atmospheric Gases

• nitrogen (N₂)
• oxygen (O₂)
• argon (Ar)
• water vapor (H₂O)
• carbon dioxide (CO₂)
• neon (Ne)
• ozone (O₃)

Other Atmospheric Gases

• carbon monoxide (CO)
• sulfur dioxide (SO₂)
• ammonia (azane) (NH₃)
• nitrogen dioxide (NO₂)
• xenon (Xe)
• radon (Rn). Radon gas is radioactive: emission rates exceed X rads per hour.
• hydrogen (H₂)
• hydrogen sulfide (H₂S)
• helium (He)
• methane (CH₄)
• nitric oxide (NO)
• phosphine (PH₃)
• hydrogen peroxide (H₂O₂)
• nitrogen dioxide (NO₂)
• ammonium hydrosulfide ((NH₄)HS)
• ammonia hydrosulfide (H₅NS)
• nitrogen trichloride (trichloramine) (NCl₃)
• chlorine (Cl)
• ethane (C₂H₆)
• acetylene (C₂H₂)
• diacetylene (C₄H₂)
• propane (C₃H₈)

Gas Giant Atmospheric Composition

• hydrogen (H₂)
  • (primary component of gas giant atmospheres)
• helium (He)
  • (major component of gas giant atmospheres)
• methane (CH₄)
  • (minor component of gas giant atmospheres)
• carbon monoxide (CO)
  • (minor component of gas giant atmospheres)
• ammonia (NH₃)
  • (minor component of gas giant atmospheres)
• water vapor (H₂O)
  • (trace component of gas giant atmospheres)
• neon (Ne)
  • (trace component of gas giant atmospheres)
• ammonia hydrosulfide (H₅NS)
  • (trace component of gas giant atmospheres)

Potential Atmospheric Taints

• the extremely high atmospheric pressure, which causes tremors, drowsiness, breathing difficulties (including oxygen toxicity) and decreased neural activity.
• the low percentage of atmospheric oxygen.
• the high percentage of atmospheric oxygen (oxygen toxicity).
• the high percentage of atmospheric carbon dioxide / carbon monoxide / sulfur dioxide / hydrogen sulfide (typically of volcanic origin).
• the high percentage of inert gases, principally argon / neon / xenon.
• trace airborne contaminants of organic origin that produce a psychological response in humans. Effects might include euphoria, mania or hallucinations, and range in severity from mild to extreme.
• an extremely unpleasant odor (floral fragrances / excrement / sulfur compounds) that triggers a gagging reflex in humans.
• large amounts of airborne silicates and dust.
• concentrations of airborne heavy metals.
• airborne radioactive dust: radiation levels exceed X rads per hour.
• the relatively high levels of background radiation: emission rates exceed X rads per hour.
• the lack of water vapor in the atmosphere.
• concentrations of airborne toxins of organic origin.
• airborne pathogens.
• allergenic spores and pollens of organic origin.
• high concentrations of chlorine and fluorine, typically of geochemical origin.
• nitrogen compounds (ammonia, nitrogen monoxide).
• pollution, current or past, typically of industrial origin

Abiotic Oxygen

• The oxygen in the atmosphere is abiotic in origin, produced by the photocatalytic reaction between the high levels of UV energy radiating from the star and titanium dioxide (TiO₂), which is found in surface minerals such as ilmenite.
• Oxygen contained deep within the world's interior is released by outgassing and serves to renew the atmosphere: it continuously reacts with surface materials and other atmospheric gases, gradually reducing the percentage of oxygen in the air.
